Patent number: 11879750Abstract: A method and apparatus for measuring a distance to an object, be a device (100) having at least two cameras (104, 106), is described. One or more first images including the object are acquired by a first camera of the device and one or more first reference images are acquired by a second camera of the device, while the device is in a first position. One or more second images including the object and one or more second reference images are acquired by cameras of the device, while the device is in a second position, different from the first position. Based on the first and second reference images, information on the displacement of at least one camera of the device between the first and second position are determined. The distance from the device to the object is calculated based on the first and second images including e object and the determined information on the displacement of the at least one camera.Type: GrantFiled: May 20, 2020Date of Patent: January 23, 2024Assignee: SNAP INC.Inventors: Eyal Zak, Ozi Egri

Publication number: 20230388632Abstract: A method for limiting motion blur in a visual tracking system is described. In one aspect, the method includes accessing a first image generated by an optical sensor of the visual tracking system, identifying camera operating parameters of the optical sensor for the first image, determining a motion of the optical sensor for the first image, determining a motion blur level of the first image based on the camera operating parameters of the optical sensor and the motion of the optical sensor, and adjusting the camera operating parameters of the optical sensor based on the motion blur level.Type: ApplicationFiled: August 14, 2023Publication date: November 30, 2023Inventors: Bo Ding, Ozi Egri, Matthias Kalkgruber, Daniel Wolf

Patent number: 11816853Abstract: Various embodiments provide systems, methods, devices, and instructions for performing simultaneous localization and mapping (SLAM) that involve initializing a SLAM process using images from as few as two different poses of a camera within a physical environment. Some embodiments may achieve this by disregarding errors in matching corresponding features depicted in image frames captured by an image sensor of a mobile computing device, and by updating the SLAM process in a way that causes the minimization process to converge to global minima rather than fall into a local minimum.Type: GrantFiled: March 12, 2021Date of Patent: November 14, 2023Assignee: SNAP INC.Inventors: David Ben Ezra, Eyal Zak, Ozi Egri
